Microsoft Exchange Server stands as Microsoft Corporation’s sophisticated email messaging solution. Users’ emails and associated content find their storage within their dedicated mailboxes, residing within .EDB files on the Exchange Server.
Regrettably, Exchange Server is susceptible to damage caused by a multitude of logical and physical factors. When such issues arise, the Information Store, acting as Exchange Server’s vital repository, often bears the brunt of the impact. The Information Store is the guardian of the public folder store, safeguarding critical data. Should any complications surface within this core component, you may encounter the following challenges:
To resolve these issues, you should initiate a database restoration from an offline backup. Upon completing the restoration process, when you proceed to run the Information Store Integrity utility (Isinteg), you may encounter the following error message:

After completing these steps, the database returns to a consistent state, allowing the information store to start successfully. Nevertheless, there may be instances where these steps alone do not resolve your issue. In such cases, you should consider repairing the priv.edb and pub.edb files using Kernel for Exchange Server, widely regarded as the premier Exchange Recovery software. This robust tool excels in addressing Exchange dirty shutdowns, checksum errors, and facilitates deleted mailbox recovery. Moreover, the software not only rebuilds the Exchange Server database but also securely preserves each recovered mailbox from EDB to PST file for your convenience.
